the eyePhone 2.0 while Mom looks on satisfied. Continuity Bender's good twin Flexo makes a brief cameo in one of the recycling bins. Cultural references Most of the episode focuses on parodies of the iPhone and Twitter, renamed the eyePhone and Twitcher respectively. The eyePhone is placed directly in the eye, hence the name. Fry asks, "Since when is the internet about robbing people of their privacy?", to which Bender replies, "August 6, 1991", which is the date that Tim Berners-Lee announced the World Wide Web project and software on the newsgroup alt.hypertext.
